ultiplayer housing?

Hello I am currently working on a rpg type of game and im wondering if its possible to have housing like in everquest 2 or final fantasy online where each player has there own instance of a room that they can decorate and be able to invite other players to come into there room.

I personally would use a house that is part of game world’s level construction, with the interior only accessible to the player owner. But, if you’re pursuing the traditional implementation, I believe it uses a separate map instance. You could follow suit using a separate map, retaining the game and player state in the Game Instance.
